The fan explained after the brutal battle they think the Night King will rise to the leadership.

The viewer theorised: “We see an empty throne room at the Red Keep.

“Then we are shown a pair of black boots walking on the carpet leading to the Iron Throne. It's the Night King!

"The White Walkers have won. The Night King sits on the Iron Throne as the camera zooms out. Fade to Black.”

This theory is based on the idea the Night King will be the victors in the war, leaving Jon Snow (played by Kit Harington) and Daenerys Targaryen (Emilia Clarke) in a bad way.

However this does also leave matriarch Cersei Lannister (Lena Headey) in the dust as well - but who would have taken her out?

Fans on the forum went on to debunk to the theory, saying: “Not going to happen. We already know that the ending will be a bittersweet one.”

While another gave their own idea, saying: “My guess is Dany sitting on the throne and burning Cersei, Tyrion [Peter Dinklage], Jaime [Nikolaj Coster-Waldau] and Varys [Conleth Hill] alive despite some of them helping her in the war.

“She won like we hoped but in winning became what she fought.”

This follows the theory Jon and Dany will be separated in the next series.
